i m trying to make a function which will calculate size of each node of an ordered statistic tree . here size refers to the number of nodes in left sub tree and right sub tree plus one...
but whenever i call this function compiler gives error....and program terminates at line:
if(ptr->lc==NULL && ptr->rc==NULL) -
size(struct node *ptr)
-
{
-
if(root==NULL)
-
{
-
-
return 0;
-
}
-
if(ptr->lc==NULL && ptr->rc==NULL)
-
ptr->size=1;
-
if(ptr!=NULL)
-
ptr->size=(size(ptr->lc) + size(ptr->rc)+1);
-
-
}
-
plz help out by advising me

Please use the [code]...[/code] tags provided.
What compiler error do you get?
What do you think this function does it it is called with a NULL pointer?

for your convenience ,to understand wat actually is done...i m putting the whole program :
and the error is general protection exception and line :if(ptr->lc==NULL && ptr->rc==NULL) i.e. line no 68..
is highlighted...i want to know what is wrong....

I have removed you code because a) it is against our posting guideline to post the full code solution to what may be a coursework problem and b) it is not required your original snippet contains all that is required to diagnose the problem.
A "general protection exception" is not a compiler error it is a runtime error, getting the terminology right will help in getting your problem fixed.
And I ask you again what do you think is happening in your function when it is called with a NULL pointer, i.e. when ptr == NULL? If it isn't obvious to you then I suggest you step through each line of code in the function on paper executing it as your processor would.
No its not dude,
I believe the rules say, when you are asking a question it is alright to post entire code. The rules are asking the experts not to post entire code solutions, and that makes sence.
edit:
Sorry guess the rule was changed again. My bad... dont agree with it tho, if you are asking a question, should be aloud to post full code. anyways.

Nope they have been that way since about this time last year, I should know I wrote them :D
It's like that for the protection of the poster as much as anything else.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
